Animal populations are roughly half the size they were in 40 years ago – a 52% decline between 1970 and 2010. Terrestrial species have declined by 39%, freshwater species by 76%, marine species by 39%. The biggest recorded threat to biodiversity globally comes from the combined impacts of habitat loss and degradation, driven by unsustainable human consumption, plus the impact of climate change.
In Ghana, the lion population in one reserve is down 90% in 40 years.
In West Africa, forest felling has restricted forest elephants to 6-7% of their historic range.
Globally, habitat loss and hunting have reduced tigers from 100,000 a century ago to just 3,000.
Just published is the 2014 Living Planet Report produced by WWF in collaboration with the Zoological Society of London and the Global Footprint Network. The report uses the global Living Planet Index as a measure of the health of over 10,000 populations of more than 3,000 species to track changes in wildlife populations.
